I designed my own Wheel Button box and I looked at other designs and tried to improov or make it my style from their concepts. I Used TPU to print the paddles and they are awesome. No Supports and 40 or more infill. Shifters are same basic design but I tried to make it better. Let me know if you need anything changed or just something new.
